In 2019, compared to other RHP:
Their sinker has heavy sinking action, has slight armside run and has slightly above average velo. Their cutter generates more whiffs/swing compared to other pitchers' cutters, has well above average velo, results in somewhat more flyballs compared to other pitchers' cutters and has some natural sink. Their fourseam fastball has heavy sinking action, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers and has essentially average velo. Their change has an obvious armside fade, dives down out of the zone and is much firmer than usual. Their slider is basically never swung at and missed compared to other pitchers' sliders, sweeps across the zone, has exceptional depth and results in many more groundballs compared to other pitchers' sliders.
